Electromagnetic wave combining device and television broadcast transmission system using same |
摘要 |
Apparatus is provided for allowing two high frequency signals from two separate sources to be combined for simultaneous propagation through a common propagation medium such as an antenna or transmission line, while maintaining isolation between the signals at the inputs of the sources and preventing unwanted interference and resulting distortion. The apparatus includes an orthogonal mode converger which receives two combined electromagnetic energy waves having orthogonally disposed electric field vectors and incrementally converges them to the same direction through a varying cross-section waveguide structure.
